Emmenopterys henryi is a species of flowering plant in the Rubiaceae family. It is found in the temperate parts of central and southern China and in Vietnam. It is a deciduous tree with opposite leaves and can attain heights of 45 m and grow to a 1000 years old. The epithet is named after the Irish botanist and sinologist Augustine Henry.

Emmenopterys henryi in Europe[edit]

The first introduction to Europe was 1907 to England by Ernest Wilson.[1][2] They are noted for their rare flowering. The first time that Emmenopterys henryi flowered in mainland Europe was 1971 in the arboretum of Villa Taranto on Lago Maggiore.[1][2] A specimen in Cambridge flowered in 2012, after 30 years, only the fifth flowering in the UK.[3] In 2013, a tree flowered for the fourth time in the Arboretum Kalmthout in Belgium. This was unexpected, since the flowers only appeared in September, which is quite late.[4]
